This application provides a sampling component, including a body portion and a lap portion. The body portion is configured to transmit a sample signal. The lap portion laps the body portion at one end and laps a point for sampling at the other end, to acquire the sample signal; and the lap portion is provided with a fusing structure configured to implement fusing protection on the body portion.

An energy cell holding device for an energy storage device, in particular a rechargeable battery pack, is disclosed. The energy cell holding device includes at least one cell holder unit for receiving at least one energy cell, the cell holder unit having at least one cell holder element which at least partially delimits at least one energy cell receiving region, in particular a single energy cell receptacle, for the energy cell. The energy cell holding device further includes at least one clamping unit which has at least one clamping element provided for clamping the energy cell which can be arranged in the energy cell receiving region in the cell holder element when the energy cell is arranged in the energy cell receiving region. The clamping unit has at least one further clamping element which is designed to additionally clamp the energy cell which can be arranged in the energy cell receiving region.

A power storage apparatus has a case accommodating an electrode assembly, and a release valve present in the wall of the case. The electrode assembly includes electrodes. A shielding member is arranged between the inner surface of the wall and the end surface of the electrode assembly. A point located in a center of the case in a front view of the case taken in the stacking direction of the electrodes and located in a center of a dimension of the electrode assembly in the stacking direction is a center point, and a region surrounded by a plane connecting the center point and a contour of the pressure release valve at a shortest distance is a three-dimensional region. The shielding member includes a shielding portion that entirely covers a cross section of the three-dimensional region along the end face of the electrode assembly.

A battery use system includes a battery removably mounted on an electric power device, a charging device configured to charge the battery, and a server configured to communicate with the charging device. The charging device is configured to transmit the identification information of the battery accommodated in the accommodation unit to the server via a first communicator and control charging of the battery and/or detachment of the battery on the basis of reception information received by the first communicator from the server. The server is configured to determine whether or not the charging of the battery and/or the detachment of the battery accommodated in the accommodation unit are available on the basis of the identification information received by a second communicator from the charging device and provision information provided from an information provider and transmit transmission information on an availability determination result to the charging device via the second communicator.

A protection assembly of a battery module and a battery module are provided, which include a base disposed with a supporting portion, an accommodating portion, and a separating portion. The supporting portion is configured to dispose a positive lead and/or a negative lead of a busbar. The accommodating portion is configured to accommodate a low-voltage connector for transmitting a signal of the battery module to a battery management system. The supporting portion and the accommodating portion are located on the same side of the battery module. The separating portion is located between the supporting portion and the accommodating portion, and is configured to separate the low-voltage connector from the positive lead and/or the negative lead. In the protection assembly of the battery module, the positive lead and/or the negative lead and the low-voltage connector are respectively disposed on the supporting portion and the accommodating portion.

A battery module includes a thermal conductive housing. A plurality of cells are arranged within the housing. An electrically insulated bottom cell holder is located between the plurality of cells and the housing. The bottom cell holder has a network of positions in which each of the plurality of cells are inserted and held. Each of the positions has an offsetting member that creates a space between the plurality of cells and a first side of the housing. A thermal adhesive occupies the space, thereby fixing each of the plurality of cells to the housing. Other aspects are described.

A battery holder may include a negative electric terminal that includes a first coiled spring, a positive electric terminal that includes second coiled spring, and a pin that aligns mating of the negative connector and the positive connector. Other aspects are described and claimed.

A sealed battery disclosed herein is provided with an electrode body, a battery case, and an insulating holder. Round sections, having a curved surface, are formed between an inner surface and a bottom surface of the battery case. Deformation portions protruding towards the center, in a width direction, are formed on the inner surface of a lower end section of the insulating holder. A lower end section of a positive electrode connection portion and a lower end section of a negative electrode connection portion are press-deformed towards the center, in the width direction, by the deformation portions of the insulating holder. It becomes accordingly possible to suitably prevent short-circuits between the electrode body and the battery case, even when clearances within the battery case are made small and a width dimension of the electrode body is made large. Energy density can be suitably increased as a result.
